Unformatted text preview: ( lens grows forward w/ age ) Vitreous POSTERIOR Chamber: jello-like –age watery (liquefies) Macula / Fovea (pit): center of retina, highest density of photoreceptors Visual Acuity & Color Vision best at fovea! Two kinds of photoreceptors in the retina Rods-night-20/200 grayscale Cones-day-20/20 color 3 types: blue, green, red rods (most sensitive to light) > cones 15˚ blind spot: NO photoreceptors Eye Movements-“pursuit” follow; “saccade” jump Divergence vs Convergence (allows stereo/3D vision)...
